COMPOSITE MOLDED LENS AND METHOD FOR MANUFACTURING SAME

摘要

Bonding performance between a lens body and a lens frame is improved. In a composite molded lens (10), a press-formed lens body (14) is integral with an injection-molded lens frame (15). The lens body (14) has a lens portion (12) and a flange portion (13) surrounding the lens portion. Eight projections (16) are radially formed on a top surface of the flange portion (13). The height of the projection (16) increases toward an outer peripheral edge side of the flange portion (13). A recess (18) is formed on an outer peripheral edge face of the flange portion (13) and located at a position on a line extending from the projection (16). The recess (18) increases torsional resilience of a joint surface and strengthens bonding force.
